<u><em>Answer:</em></u>
70
<u><em>Explanation:</em></u>
Assume that the number we are looking for is x
one tenth is interpreted into
Now, we know that one tenth of the number is 7, this means that:
* x = 7
Solve for x by multiplying both sides of the equation by 10, we get:
* x * 10 = 7 * 10
x = 70
Hope this helps :)
He makes $375 a week. Since we know he makes the same amount each week, you set up the equation 12m = 4500. To solve, just divide 4500 (total amount made) by the 12 (the amount of weeks) and you get $375 per week.
y = a sin b(x±h) ± k
a : amplitude => take absolute value
b : angular frequency
h : horizontal shift ( phase shift). (+ left, - right)
k : mid. line or vertical shift ( + up, - down)
period: the length of one cycle
period = 2π/b ( for sines, cosines. if tangent : p = π/b)
Offer 2 is the best.
To find how much you get off of each car, multiply the amount by the fraction. For offer 2, do £11 100×⅓ and you should get 3700.
For offer 3 do £9600×¼ and you get 2400.
Since you get the most money off with offer 2, that would be the best offer.
Hope this helps :)
Answer:
x = 6
Step-by-step explanation:
Based on the two secants intersecting theorem, thus:
(x + 4)*4 = (3 + 5)*5
x*4 + 4*4 = (8)*5
4x + 16 = 40
4x + 16 - 16 = 40 - 16 (subtraction property of equality)
4x = 24
4x/4 = 24/4 (Division property of equality)
x = 6
